 color is really dirty white but is so evenly and closely overlaid with 

 bluish fuscous scales as to give the impression of an even color to the 

 naked eye; three complete, broad, blackish fuscous lines run obliquely 

 across the wing, the first from basal fourth of costa to the middle of 

 dorsum, the second from the middle of costa to just before tornus; 

 these two are tolerably straight and nearly parallel; the third line 

 runs from apical fourth of costa to tornus and is outwardly curved 

 and sinuated; a series of small, black, equidistant marginal dots 

 around apex and termen ; cilia light gray. Hindwing light ochreous 

 fuscous. Abdomen dark fuscous above, silvery white on the under-
